Shed Skin is an experimental Python-to-C++ compiler. It can convert many Python programs into optimized C++ code, without any user intervention such as adding type declarations. Its main purpose is to optimize algorithmic-like Python code, by applying advanced global type inference techniques.

What do you think a compiler is? This is a compiler, plain and simple. Lots of compilers target C instead of ASM, usually because that way they don't have to implement all the optimizations the C compiler does. They're still compilers.
